IMPROVEMENT IN CHEST-EXPAN'DERS.

To @ZZ whom t may concern,.-

Beit knownY that I, SAMUEL M. BAENETT, of the city and State of N ew York, have invented certain Improvements in `Chest-EX- panders, of which the following is a speciication.

My invention relates to the mode of attaching the rubber' or elastic band to the handles by means of a pin, a cylindrical chamber, and groove, thereby allowing one or both ends of the band to be detached when necessary, the same being an improvement upon the device shown in Letters Patent granted to me February 5, 1867, No. 61,702.

Figure l is a side elevation of the apparatus when complete, embodying my invention, and showing its mode of attachment. Fig. 2 is a view of the elastic band, showing the loops at each end. Fig. 3 is an elevation of the handle, showing its cylindrical chamber and groove. Fig. 4 is a pin belonging thereto; and Fig. 5 is a crosssection at the line x x, Fig. 3.

A is the handle, and B the pin, all of which may be made of wood or other suitable mate-V rial, and of any convenient size or form.

c is the elastic band; d, the loop at each end of the band; e, the cylindrical chamber, bored venient for a variety of exercises, and the elastic band can by this contrivance be changed for a weaker or stronger one, and if the rubber should become imperfect or broken a more perfect one can besubstituted.

I claim as my invention- The handles A A, with their cylindrical chambers e e, grooves f f, and pins B B, substantially as and for the purpose hereinbefore set forth.

Signed by me this 2d day of March, A. D. 1871.
